this was my favorite of projects that judges voted through to semii-finals emerging market track of mit100k accelerator (there were a few of my favorites 1 2 that I got outvoted on) but this one seemed a massive health problem, one near solution , and on my pro-youth economics maps exchanges between chinese and mit youth are one of most positive flows for the world

DSL Waste to Energy Solutions

The Idea

DSL Waste to Energy Solutions tackles China's most prominent food safety problem – 1 out of 10 restaurants use gutter oil for cooking, which is oil collected from restaurant leftovers and sewers. Containing cancer-causing contaminants, gutter oil has recently stirred public outcry. Despite numerous government crackdowns, China lacks technologies that eradicate gutter oil from its origin.
DSL is engineering an on-site food waste-to-energy innovation that repurposes waste cooking oil as an energy resource for providing restaurant heating needs, therefore preventing recirculation of the oil. Our solution is distinct in its economic incentives to customers and the automation of waste treatment processes.

another mit100k semi-finalist that i thought particularly interesting
First, working with local waste pickers, we are devising a unique waste collection model mobilizing the entire slum to turn in their waste, and not just the few who can afford the service. Second, we are exploring the under-appreciated organic waste, turning it into a safe and affordable cooking fuel for local households. This will avoid charcoal production from wood and save trees, while serving wide-ranging social issues such as increasing local income, reducing greenhouse emissions.

The Team

We are a diverse team of MIT and Harvard students as well as Kenyan community mobilizers. We come from backgrounds in engineering, management, public policy, and environmental studies, but we are united in our passion for waste and its processing. Our cumulative past experiences include consulting for Deloitte, doing financial trading, as well as working with the U.S. foreign service. We have worked with MIT's D-Lab and Engineers Without Borders

Green Power

Competition Year: 2013

Our system provides an efficient system to treat black liquor waste from paper mills and generate back-up power

Our Pitch

In many developing countries, the emission of industrial waste is often regulated less rigorously. As a result, industrial effluent has negative environmental and health externalities that run in the millions of dollars.
For example, paper mills produce waste called black liquor. While some technologies are used to recover useful materials from black liquor but they are very inefficient and capital-intensive, and a large part of black liquor waste is spewed into the environment.
In addition, a paper mill loses $27,000/day due to inconsistent power supply. While many homes and industries are equipped with diesel back-up power generators, electricity generation from diesel is very expensive—sometimes almost 50 cents per kWh!
Our proposed solution addresses both the environmental pollution and power outage, by monetizing the environmental externality and using it as a back-up power source.
Our system would improve the efficiency of earlier technology (of converting organic residues to fuels) and will also recover inorganic pulping chemicals (unlike existing technologies). The remaining organic waste can then be processed (via biodigestion) into natural gas (e.g. methane), which serves as a back-up power system with a much lower operating cost compared to diesel generators. Enough gas will be stored/compressed to ensure that the mill can effectively tide over a typical power outage.


Reduce externalities associated with spewing black liquor into the environment and provide clean backup

Who We Are

Mohit Kansal
Mohit is an MBA Candidate 2014 at MIT Sloan School of Management. Prior to MIT Sloan, he spent the summer of 2012 working for a solar startup in New Delhi, India. Prior to that, he spent five years working in two investment banks in London and Hong Kong. Mohit is a Computer Science Engineer from Indian Institute of Technology Bombay (2007). Mohit is the business person on our team who is responsible for analyzing business opportunity in target country (India). He is a native Hindi speaker and has a strong network in India that our team can leverage to get information and reach out to industrial contacts.
Kevin Kung
Kevin is a graduate student at MIT Biological Engineering. He is passionate about innovations and entrepreneurship for the global poor. In addition to his research in biophysics, he has been involved, since 2005, with various engineering projects in the developing world, including a rural electrification and lighting system in Peru, water filtration in Uganda, interlocking stabilized soil blocks in Ghana, and a manually operated centrifuge design in Nigeria. Kevin has been focusing on social projects during his time at MIT and has significant expertise in waste to energy technologies. He is responsible for analyzing composition of waste (black liquor) and designing solutions to efficiently process it.
Vincent Liu
Vincent Liu is a doctoral student at MIT studying Electrical engineering and medical devices. He is experienced in both technology and business development for the developing world; he was previously involved with a medical device startup focusing on affordable skin grafting technology and team Salud del Sol, a team developing solar-powered autoclaves for use in the developing world. Vincent is responsible for the electricity generation aspects of the project. His electrical engineering expertise is most relevant in methods of converting waste to energy and storing energy efficiently.
